🎮 Game Error Codes What it means & how to fix it

Once Human Errors

Almost every Once Human error is a connection or login problem between your client and NetEase's servers — 'Logging in, please try again later', Error 3 and network errors all mean the sign-in or session couldn't complete. Servers get overloaded at launch and after big updates. Here's what each common error means and the fastest fix.

Error codes

Logging in, please try again later The login attempt didn't complete

Cause: Server load or a Steam-login service issue — this hit many Steam players in August 2025 and needed a server-side fix.

Fix:
  1. Repeatedly retry the login — it often connects after a few attempts during busy periods.
  2. Repair the client (launcher repair) and verify files in Steam.
  3. Check the official Once Human channels for a login-service notice.
Error 3 Login error

Cause: The sign-in handshake failed — server busy, a firewall block, or an account-service hiccup.

Fix:
  1. Restart the game and retry the login.
  2. Allow the game through your firewall and disable any VPN.
  3. Check server status before retrying.
Error 101 Connection error after the loading screen

Cause: The client lost or couldn't complete its link to the server after loading in.

Fix:
  1. Restart the game and reconnect.
  2. Power-cycle your router and switch to a wired connection.
  3. Flush DNS (ipconfig /flushdns) or use 8.8.8.8 / 1.1.1.1.
Network Error / Connection Failed The client can't reach or hold a connection to the servers

Cause: Servers down or in maintenance, an unstable connection, or firewall interference.

Fix:
  1. Check server status on the official site or social channels.
  2. Update the game and verify your internet is steady.
  3. Adjust network/firewall settings and disable VPN if servers are up.

Fixes that work for most Once Human (Steam PC) errors

  1. Check the game's server status first (official status page, or the studio's support/X account) — most named connection errors are a maintenance window or outage, and no local fix will help until servers are back.
  2. Restart the game and your PC/console, and power-cycle your router — a fresh connection clears the majority of temporary login and connection errors.
  3. On PC, allow the game and its launcher through your firewall and antivirus, and disable any VPN or proxy — these block the authentication handshake behind many 'can't connect' codes.
  4. Flush your DNS (Command Prompt: ipconfig /flushdns) or switch to a public DNS like 8.8.8.8 / 1.1.1.1 if the game can't reach its servers.
  5. Verify/repair the game files (Steam: Properties -> Installed Files -> Verify; Epic: repair) if the error points at a corrupted install or update.
